I have. Here is a picture of the 55-gallon plastic drum I am using. It works well for me. This is a picture of when I first bought and set it near my stock tanks. I'll get another picture of how it looks all set up a little later.
I put a Hydros ATO kit on it, and it works well. I have a feed from a BRS 7-stage RODI unit in another basement area. I am converting it from Hydros to GHL equipment as I transition my control system to GHL.
